I thought this guy said that he was snarfing the articles from a Unix box
and not using RNews.  Thus, renumbering isn't too hot a prospect for him.

Why limit things?  It's not like storeing 32bits in ascii for a filename
will make any difference.  The bytes are allocated anyway on the disk.  And
so the dnewsrc file might be a tad bigger.  The only place I can see this
making any difference is in lining up the article counts in the newsgroup
select window.  But this could be done dynamically by figureing out which
newsgroup has the largest number printed and then space in all news groups
accordingly.  Maybe it's just me, but I can't see any good reason to not
use a full 32 bits.  And I'd seem to me you have to go more out of your way
to add support for things to roll over than to just to dynamic column
lineup...
